Earlier today we took a look at some browser benchmarks, repeating a test done earlier by Microsoft to show the superiority of Windows Phone 7 at rendering HTML5. The results made it appear as though Apple had moved up to the top spot when looking at its performance under iOS 5, but it turns out things are a little more complicated than that, and its hard to argue in favor of iOS dominance at this point.
In the first demo, IE9 on WP7 performed at 25FPS, and while that easily beat iOS 4, iOS 5 is apparently capable of 31FPS performance. Problem is, that’s not quite the fair comparison. The Next Web wanted to see what’s going on, and while it confirmed Apple’s scores (its best test showed an even higher 32FPS), Microsoft managed to beat even that.
It seems that the test itself may not be the most accurate benchmark, since on a developer’s Mango device, IE9 returned scores ranging from 25FPS to 45FPS; it’s wildly inconsistent. So yes, while at this point it’s possible for Safari to deliver a bit of an edge over IE9, it’s just as likely for IE9 to soundly trump Safari’s performance.
Clearly, we need a better benchmark, and should wait for the final releases of these browsers, before passing judgement.
